Hi, I'm connecting Teams with kamailio server. From Kamailio to teams I have no problems, but from teams to Kamailio yes. Drop the call..

With ngrep I see that:

INVITE:

[image: imagen.png] 200 OK:

[image: imagen.png]

I never received ACK..

In my configuration:

Kamailio.cfg:

#!KAMAILIO #!define WITH_TLS

event_route[tm:local-request] {

if(is_method("OPTIONS") && $ru =~ "pstnhub.microsoft.com") { append_hf("Contact: sip:FQND:5061;transport=tls\r\n"); } xlog("L_INFO", "Sent out tm request: $mb\n"); }

request_route{

remove_hf("Route"); if (is_method("INVITE|SUBSCRIBE")) { xlog("L_INFO","$fU is trying to call to $rU con valores $tu\n"); $ru = "sip:" + $rU + "@ip asterisk:port"; route(RELAY); } }

What I'm doing wrong?

I don't understand why not received ACK..

Could anyone help me?

Thanks
